Multimedia messages do not use a telephone number but rather a URL: http://mmsc.cingular.com . Perhaps you meant SMS since you mentioned text messages. MMS is designed for pictures, sounds and video although you can also send text via MMS. The SMS Service Center Number is +13123149810.

so i put in the URL and i tried to send a mms picture text but it didn't send. do i have to change the setting for Internet account? or is the picture i attached too big to be sent.

You gave few details about your situation. It would be impossible for anyone to answer your questions based upon the information you have given.

What information do u need? All i noe is I switched my fone from an AT&T LG SHINE to a unbranded Sony Ericsson P1i. I am able to text message people, but when I try to send a mms message it fails. You already gave me the url which I put in and it still didn't work. for Setting up the MMS account there is another option below where u put in the url that says internet account.

This is the first time you identified which phone model you are trying to setup. Sony Ericsson has an online service for sending the settings to the phone: Sony Ericsson - Support - Phone settings

Be aware that the phone does not have either the United States 3G bands nor the 850 MHz GSM band.

Thanks man, well it successfully sent my GF text me saying she got the picture. So if it doesn't have the 3G band or GSM band wat does that exactly mean?

In some areas your phone will not work at all because AT&T might be using the 850 MHz band instead of the 1900 MHz band. The data transmission rate will be slower if your phone does not have 3G. It has the 3G band for Europe and Asia only.
